About Sour Alien Auto

Does Sour Alien finish outdoors in Ireland? It does, planted out at the end of May and cut by early October. The 40/60 balance handles an Irish season without special treatment, which is most of the reason to choose it. Bloom takes 65-75 days, so the harvest date is set by the calendar far more than by your technique.

What should I expect to take off it? up to 300 g/m2 indoors and up to 200 g/plant outdoors are the published figures, and both assume a full light or a full season plus a root run to match. A tunnel gets you most of the way to the outdoor number; a windowsill will not. At 27% THC the effort is well spent either way.

Is it a sensible first grow? Reasonably. Anyone who has finished one grow will manage this one; it asks for consistency rather than expertise.

Other questions that come up about Sour Alien

Soil or coco? Coco with fertigation at EC 1.4-1.8 through bloom if you are there daily and want speed. Peat-free soil with slow amendments — fish, blood and bone, seaweed meal, rock phosphate — if you are not, and want flavour. Both suit this hybrid; the deciding factor is your week, not the plant.

How does it handle the weather here? Hybrid vigour covers most of what an Irish summer does. Keep the root zone under 28°C and do not transplant into a warm spell.

When does bloom feed start? Within a week of the first pistils. The 40/60 balance shifts demand quickly at the transition — phosphorus and potassium up, nitrogen down. Soil growers top-dress; coco and hydro switch formula immediately.

Tunnel, outdoors or indoors? A tunnel is the best value of the three here. Indoors you own the 65-75 days of bloom completely; outdoors the plant gets light no lamp matches and can reach up to 200 g/plant, and pays for it in rain. Flowering: 65-75 days. Indoor yield: up to 300 g/m2. Outdoor yield: up to 200 g/plant. Plant height: Short. Rated easy difficulty.

Flavour, aroma and effect

Sour Alien arrives in order. The first draw at 27% THC gives peppercorn heat that lands at the back of the throat. The euphoric, uplifted, calm character follows in minutes, as head and body together. Thinking stays clear while the muscles let go by degrees, which is what makes the dose, rather than the genetics, the thing that decides the evening. Limonene underneath contributes a lift that stops it going heavy.

Terpene breakdown

Primary: Caryophyllene · Secondary: Limonene · Tertiary: Myrcene. The three shift relative to each other across the cure. Straight off the dry the caryophyllene dominates; three or four weeks sealed in glass at 16-18°C and the myrcene underneath comes up to meet it. Vaporising between 180°C and 195°C catches the widest span, because heat takes the lighter myrcene molecules first.

Who it suits

Who does well with Sour Alien? Back-garden and balcony growers in Dublin, Cork and Galway. Anyone who wants a crop dry and put away before the autumn closes in. Indoor growers short of headroom. The autoflowering genetics run to their own clock, so there is no schedule to manage and no anxiety about light leaks. Rated easy, which means a moderate learning curve that rewards attention without needing specialist kit.
